MSM specific config settings

Question

Is it possible to only target specific MSM sites, as opposed to all sites.

I have two subdomains and a www site using the same MSM installation.

Is it possible to share a cookies between sub1.domain.co.uk and sub2.domain.co.uk but not affect www.domain.co.uk

Basically i want my members to be able to login to sub1 and automatically be logged in for sub2 domains but not www.

You can use the $assign_to_config array in each site's index.php and admin.php files to set some per-site config items. (See docs.)

But you might have better luck using a switch statement in your main config.php file, e.g.,

switch($_SERVER['SERVER_NAME'])
{
    case 'www.domain.co.uk':
        $config['foo'] = 'bar';
        break;
    case 'sub1.domain.co.uk':
        $config['foo'] = 'baz';
        break;
}

For sharing cookies, look at the $config['multi_login_sites'] variable, e.g.,

$config['multi_login_sites'] = 'http://sub1.domain.co.uk|http://sub2.domain.co.uk';
